How do TyreCheckers® Mechanical Tyre Pressure Indicators work?

TyreCheckers® operate on a simple spring pressure system manufactured to specific tolerances.

When the tyre is correctly inflated, the TyreChecker is all green. If the tyre pressure drops by 10 – 15% (e.g. 30psi x 10% = 3.0psi) the green indicator is replaced by an amber indicator, giving a warning that the tyre pressure is reducing. If there is a 15 – 25% reduction (e.g. 30psi x 20% = 6psi) in tyre pressure then a red indicator becomes clearly visible, giving a clear warning that the tyre pressure is now dangerously low and needs to be inflated.
